Research published by the National Fire Protection Association (NFPA) in 2021 found that 'almost three out of five home fire deaths were... in properties with no smoke alarms (41 percent) or [with] smoke alarms that failed to operate (16 percent)... Power source issues were the most common factors when smoke alarms failed to operate'.

This means that Fire Protection Groups and Fire Departments must be cautious when it comes to battery selection.  Many factors must be considered, from high performance to longevity.

Films about fictitious shrinking devices - like Honey, I Shrunk the Kids and Despicable Me - have captured the imagination of audiences for many years.  So imagine the excitement in 2011 when Chinese engineers claimed to have made the world’s first shrinking device.  While it may sound like it came from a film, the device only created the illusion of a smaller object, rather than actually shrinking it.
